What Customers Are Saying
The product appears to have mixed results. Many customers report it is an effective and easy-to-use solution for removing mold, mildew, and algae from outdoor surfaces. However, some found it did not work as well, especially on tougher stains or larger areas. The product seems to work best for lighter growth, but may require additional scrubbing or treatments for more stubborn issues. Customers note it can take several weeks to fully work, so patience is required. Overall, the consensus is the product is useful, but its effectiveness can vary depending on the cleaning needs.

Sprayed my patio wood frame and waited four days for results. I was very disappointed with the product, it didn’t remove dirt much less mold. Wasted $25, don’t recommend !

worked very well on patio umbrella
Would RecommendI saw some reviews that said it did not work so was very pleasantly surprised. Patio umbrella had a lot of green/black algae/mold. Sprayed it down and within a few days 95% was gone. Did a second application on remaining spots
Great way to clear a roof of moss
Would RecommendIs working on a pavillion roof. Needs repeated treatments, and its working.

So So Clean
Would RecommendWorks rather well, I wasn't expecting it to get brighter over time but it does. I will need another treatment because it doesn't wash like soap and bleach. It came leaking so if you have to have it delivered you may have less solution than originally intended. Bummer!!

Product Claims are not 100% accurate.
Would Not RecommendThis worked well on my neighbor's algae growth. It took some off of my deck, but left on much more than was expected. I finally had to pay to have it power washed.
